Subject: * benchmark/bm_vm1_gc_short_lived.rb: added.   These GC benchmarks do
 not reflect practical applications.   They are only for tuning. *
 benchmark/bm_vm1_gc_short_with_complex_long.rb: added. *
 benchmark/bm_vm1_gc_short_with_long.rb: added. *
 benchmark/bm_vm1_gc_short_with_symbol.rb: added. *
 benchmark/bm_vm1_gc_wb_ary.rb: added. * benchmark/bm_vm1_gc_wb_obj.rb: added.
 * benchmark/bm_vm_thread_queue.rb: added.   Thie benchmark is added to know
 how fast C verion of thread.so.
